Maria Pereira's surgical glue could completely revolutionize modern medicine
Wherever Maria Pereira goes these days—her office in Paris, a conference in Boston, or back home to Portugal—she carries around a thumb-size vial of glue. That vial, a good-luck charm, may contain the solution to one of surgery’s oldest problems: how to seal wounds and holes in the body without damaging the body itself.
The ancient Egyptians and Greeks faced the same dilemma, and coarse stitches from catgut and silk were their method of choice. The modern physician relies on a more refined technique of suturing wounds, yet it can still result in infection, irritation and scarring. Pereira, the head of research at Paris-based medical-device startup Gecko Biomedical, plans on changing that. “Innovation in science is the key to improving people’s lives,” says the 30-year-old, who grew up in the Portuguese city of Leiria and moved to Paris in October 2013 to join Gecko. The company closed its first round of funding at the end of that year, raising $11 million to advance work on surgical glues and patches for wound closure./.../

Emerging Technology From the arXivJune 30, 2015 The Social-Network Illusion That Tricks Your Mind Network scientists have discovered how social networks can create the illusion that something is common when it is actually rare. One of the curious things about social networks is the way that some messages, pictures, or ideas can spread like wildfire while others that seem just as catchy or interesting barely register at all. The content itself cannot be the source of this difference. Instead, there must be some property of the network that changes to allow some ideas to spread but not ...mais »

The UN Development Goals Miss the Point – It’s All About Power Unless you understand that the poverty of some flows from the wealth and power of others, efforts to fight poverty will not truly work. by Nick Dearden 6 Comments Far from critiquing the control of the market, the SDGs exhort world leaders to "remove market distortions" and "ensure the proper functioning of food commodity markets." This is not the way to end poverty in twenty years. (Photo: via Global Justice Now) Not many people enjoy the existence of poverty. Some think it’s inevitable, others that tackling it is politi...mais »

5 FDR Quotes On Poverty That Still Totally Hold Up It’s really quite surprising that Franklin D. Roosevelt was only considered important enough for the tiniest of American currency, because he was one hell of a President. Not only did he battle polio — POLIO — he also was a crusader for what he called “the forgotten man,” i.e. the poor. Like waaaaaay before it was cool. And get this — he didn’t even grow up poor! He just *knew that poor people needed care and then talked about it and tried to help them.* As the Presidential race heats up (bye, Scott Walker! See you in Hell!) and New Yo...mais »
